I'm curious what views of additional GK MB powered cabs would be. With a MB212, I have 500 watts through the two 12" speakers. In most cases, this alone provides me with enough power on stage, but I'm curious what benefit would a 115MBP add to the scenario. The MBP115 adds another 200 watts, but it's through a 15". Considering that I don't run the MB212 beyond a 4 level in most small venues, would there be a benefit of the 115 to add warmth and fill out the sound? Years ago, I had a GK rig with a 210 on top of a 115. I always thought the 115 filled out the sound nicely, while the 210 cut. 200 watts from a 115 seems like it would be significantly underpowered compared to the 212 cab, but should I be thinking about it from a single speaker perspective? Each speaker in the 212 is running about 250 watts, right? So, would this be more balanced? The reason I ask is that while the GK MB and MBP line seems really adaptable, there are only a few cabs that fit an equal footprint. An additional 212MBP brings the whole rig to 1000watts and that's a lot of power. A MB212 with a MBP115 is 700 watts total, but sonically, does the 115 add much?
